For what I have seen by your .csv file and by looking at your image, I can see multiple problems with the ways your are importing your schedules to your site.
First and foremost, on the Import page in the Admin Center, make sure that "First line of CSV is the header" Has the check mark in the box.
Second, your flight numbers should always be in number format, (ie. 1, 2, 3, 4, 5, 6, ...not A1, A2, A3) (when the site displays the flight numbers it WILL show them as FRO123)
Third, you are going to need to leave DISTANCE blank or actually put a number in there. (the number format can be 123 or 123.4 never text)
Forth, your flight times must be entered as time (12:00) never as text.
I have taken the first flight from your .csv, and displayed how it should look prior to export (I hi-lighted my part yellow)
